The duct further includes, in an area opposing the transfer roller, a first opening portion that is provided at a position closer to a first end side of the duct than to a second end side of the duct, and a second opening portion that is provided at a position closer to the second end side than to the first end side, in the parallel direction. The air supplied to the duct by the fan through the inflow port passes through the first opening portion and the second opening portion, and is supplied to the transfer roller.
